<p class="level0"><span Class="bold">pcap_offline_filter()</span> checks whether a filter matches a packet. <span Class="emphasis">fp</span> is a pointer to a <span Class="emphasis">bpf_program</span> struct, usually the result of a call to <a Class="bold" href="./pcap_compile.html">pcap_compile</a>. <span Class="emphasis">h</span> points to the <span Class="emphasis">pcap_pkthdr</span> structure for the packet, and <span Class="emphasis">pkt</span> points to the data in the packet. <a name="RETURN"></a><h2 class="nroffsh">RETURN VALUE</h2>
<p class="level0"><span Class="bold">pcap_offline_filter()</span> returns the return value of the filter program.  This will be zero if the packet doesn&#39;t match the filter and non-zero if the packet matches the filter. <a name="SEE"></a><h2 class="nroffsh">SEE ALSO</h2>
